How to measure....?
To measure the size for a non adjustable collar you need to measure "C" (circumference around the neck, see picture below) and enter it in the field Measurement "C". You can use a soft tape or a piece of string to measure.
Make sure that you can fit two fingers between the tape or string and the neck of your dog.
MARTINGALE AND SLIP COLLAR
To measure the size for a martingale leash or slip collar you need to measure the circumference of "A" and "B" (the widest part of the head (A) and the narrowest part behind the ears (B), see picture below).
